And yeah, 450m might be expensive, but so is all the LTE stuff. You'll
max out the legal EIRP with 450m, and get 8x8 MIMO. I think part of the
magic with LTE is that it will connect with ridiculously low signal, but
on a fixed system you probably won't really want the trashy signals anyway.
Cambium also has LTE for whatever it's worth. The CBRS version is
supposed to be available relatively soon (though I forget precisely when).
I don't know if I state it as "fewer issues since there is no EPC", but
definitely fewer complexities and fewer things to worry about. The
connection from eNB to EPC has to be /pristine/, and the EPC comes with
its own set of new terminology and new concepts to figure out.

I have seen lots to people doing 450M in CBRS stating coverage is
nearly the same as LTE but way better speeds and triple the aggregate
capacity due to mu-mimo.
Way fewer issues too since there is no EPC. Just straight layer 2 with
no bullshit.

We are looking at a new area to expand out network that has a lot
more tree cover than our current footprint. We are thinking with
the combination of CBRS and LTE, that we might be able to offer
better coverage than with traditional fixed wireless options. We
have started conversations with the following vendors, wondering
if anyone has any hands on experience with any of them and what
their impressions were:
Blinq
Airspan
Baicells
Ericsson
The Ericsson equipment is in a class by itself price wise, but the
others are similarly priced, and somewhere around double the price
of PMP 450 stuff. Normally we would add more tower sites for
better coverage, but this project will need to be done before the
end of the year and building towers isn’t an option. We have
good enough spread on the towers that we think we can do this with
PMP 450 APs, but are thinking we’d get even better coverage out of
LTE. Any opinions on the reliability and the manageability of
the four vendors above? Sorry for such an open ended question,
but not sure what to ask to be more specific. We know that we
will have the LTE stuff to deal with like access to an EPC and so
on, so not so much worried about that as more the manufacturers
themselves. Baicells concerns us as they may get lumped in with
Huawei.
Thoughts?
